Overview of worm gear flange butterfly valve

The valve plate of the worm gear butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped valve plate rotates around the axis, and the rotation angle is between 0° and 90°. When it rotates to 90°, the valve is in a fully open state. This valve is generally installed horizontally.

Commonly used butterfly valves are wafer type butterfly valve and flange type butterfly valve. The wafer type butterfly valve uses studs to connect the valve between the two pipeline flanges. The flange type butterfly valve has a flange on the valve, and the flanges at both ends of the valve are connected to the flanges of the pipeline with bolts.

Worm gear flange butterfly valve

Worm Gear Butterfly Valve Features

  • The manual butterfly valve is simple in structure, small in size and light in weight, and only consists of a few parts.
  • Just turn 90° to open and close quickly, easy to operate
  • It has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics.
  • The structure is compact and reasonable, the operating torque is small, the opening and closing is quick and flexible, the flow resistance is small, the flow coefficient is large, and the maintenance and use are convenient.

Worm gear flange butterfly valve application and scope of application

It is used for sulfur incineration, conversion and dry suction in the sulfuric acid system. It is the preferred brand of valves for sulfuric acid plants. It is considered by the majority of users as: good sealing performance, light operation, secondary corrosion, high temperature resistance, convenient operation, Flexible, safe and reliable butterfly valves have been widely used.

It is also widely used in: SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid in chemical, petrochemical, smelting, pharmaceutical, food and other industries It is used as a regulating and shut-off device on pipelines such as medium.
